BC53-10PAS-QX

Single Bipolar Transistors Overview

The BC53-10PAS-QX is a PNP medium power transistor from the Nexperia BC53xPAS-Q series, housed in an ultra-thin DFN2020D-3 (SOT1061D) leadless SMD plastic package. It features a collector-emitter voltage of -80 V and a continuous collector current of -1 A. The device includes an exposed heat sink for thermal management and offers two current gain selections; the BC53-10 variant specifies a DC current gain range of 63 to 160 at VCE = -2 V and IC = -150 mA. Qualified under AEC-Q101, it supports peak currents up to -2 A.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and availability status. Ensure the selected part number matches the required current gain bin, as the BC53-10 designation indicates a specific hFE range distinct from other variants in the series. Confirm RoHS compliance and automotive qualification requirements prior to final procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high collector current in a compact footprint. The exposed pad design necessitates proper PCB thermal relief planning to maximize heat dissipation. Verify that the application voltage does not exceed the -80 V collector-emitter rating. Consider the specific hFE bin (BC53-10) if tight gain control is necessary for amplifier or switching performance stability.

Single Bipolar Transistors Part Context

This device belongs to the BC53xPAS-Q series, which includes complementary NPN types and variants with different voltage ratings such as the BC51 and BC52 series. The PAS-Q suffix denotes automotive qualification and the specific DFN2020D-3 package type. The series is designed to replace older through-hole or larger surface-mount transistors in modern space-constrained electronic designs.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same family include BC53PAS-Q and BC53-16PAS-Q, which share the same package but differ in current gain specifications. For higher voltage requirements, consider the BC51PAS-Q (-45V) or BC52PAS-Q (-60V) variants, though these have lower voltage ratings. Always verify pinout compatibility and thermal characteristics when substituting.
